TACHINIDAE: Tachininae: Occisorini: Platytachina Malloch, 1938Platytachina major Malloch, 1938, orig. des. [NZAC].
DiagnosisCharacteristics of Platytachina include: 1. Body size 11 – 17mm; 2. Parafacials haired to about just past midway; 3. Face in profile concave and visible; 4. Face without carina; 5. Scutellum with at least 4 pairs of marginal setae; 6. Wing cell r4+5 open; 7. Female pro tarsi not dilated; 8. Male 6th tergite reduced but conspicuously exposed. Note: This genus keys out together with Chaetopletha, Neotachina, Phaoniella, Plethochaetigera, and Tachineo. It is considerably difficult to find satisfactory external characters to distinguish these genera in a dichotomous key. This difficulty is expressed by Malloch 1938 several times over as well as by Dugdale 1969. A thorough revision at the genus level is needed that includes molecular analysis, rearing and collecting of new material.
